APPARATUS FOR SUPPLY OF INK TO PENS.

SPECIFICATION forming part of Letters Patent No. 281,998, dated July 24, 1883.

Application filed January 26, 1883. (Ne model.)

Patented in England Augustin, 1882, No. 4,152; in Germany September 6, 1882,

No. 22,511; in Belgium September 7, 1882, No. 58,967. and in France September 9, 18: 3, No. 151,0]8.

To all whom it may concern:

Be it known that we, G-IBBARD Brennan Hucuns and THOMAS GARW'ARDINE, subjects of the Queen of Great Britain and Ireland, residing at I-Iampstead, in the county of Middlesex, l lngland, have jointly invented certain new and useful Improvements in Means or Apparatus for the Supply of Ink or Writing-Fluid to Pens, (for which we have obtained a patent in Great Britain, No. 4,152, dated August 31, 1882; in France, No. 151,018, dated September 8, 1882; in Belgium, No. 58,967, dated September 7, 18S2, and in Germany, No. 22,511, dated September 6, 1882;) and we do hereby declare that the following is a full, clear, and exact description of the invention, which. will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

The invention. relates to improvements in ink-supplyi ng m cans or apparatus for writingpens of the reservoir or fountain kind; and the objects of our improvements are, first, to protect the pen from corrosion by'kecping the ink out of actual contact therewith, except at or near the points or nib; and, second, to prevent flow of ink at the nib except when. the pen is in actual use in writing; third, to prevent escape of ink from the holder of the pen during carriage in the pocket, or otherwise; and, fourth, the better control of the ink in the reservoir and in its flow to the pen. We prefer to attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 shows a vertical section of the entire pen and holder. Fig. 2 shows a sectional View. Fig. 3 a side view. Fig. 4 an upper side, and Fig. 5 an under side view, respectively, of the pen and its ink-conductor attachment separated from the holder and reservoir parts. Fig. 6 shows the bag or conductor hereinafter more particularly referred to separately.

Similar letters refer to similar parts throughout the several views.

1 ing parts a and d, d and c.

a is the pen proper or nib, having its barrel portion a enveloped by one portion, 7), of the india-rubber bag I), such portion being for this purposeturncdinside out over it. The remai der of the bag does not envelop or jacket t]. pen; but its other end, I), is twice puncturei or passed through by the points of the nib a", such points entering from the outside of: the bag and emerging from the side opposite that at which it enters, thus puncturing the bag substantially transversely. This bag-enveloped pen a is then sockcted or held in the eonically-shaped opening 0 of the part c of the main holder, and this part c is screwed to the part (1 of the reservoir (1, whilethe part II thereof again is screwed to the part of the holder 0, which part c is screwed at a to the part f of a connectingplug, f, upon the part f" of which plug a perforated end piece, 9, is slid, the reservoir (1 having been iilled with ink by unscrewing the parts (7, and (a The operation of the apparatus in working is as follows: Pressure of the nibs on the surface to be inscribed causes their separation, and this opening of these nibs also opens the elastic end of the bag I) through which. they pass, and so permits ink to ilow out in a thin stream, while their removal from the written surface permits the nibs and the enveloping end of the bag to reclose, stopping the flow of ink. lhe perfect action of these parts in precluding the ilow of ink except in actual use is secured by dipping or coating the pen and bag with india-rubber or other suitable elastic solutionai'tcrthey have been attachedtogether, completing the seal .ing of the closed .nibs with the perforated small end of theink bag. Ink to the ink-bag b ilows therein by its open end I) from the ink-reservoir (Z down the channel or chamber 0*". Chambers (5", c", and arr formed by the spaces left between the adjoind, c, and f, f and g and the chambers c, a", and g are connected forthe passage of air by channels d a f", which air enters by the perforations 9*, while the chamber 0 further serves as a catch-chamber or interceptor to intercept ink that may escape through these air-passages in what would be an undesirable and inconvenient direction.

with danger of eventual escape into the pocket or hand. For still greater security in some cases, we slide or otherwise secure over the outer end, an unperforated cap or cover, (not necessary to be shown,) and when the pen is out of use such cap or cover and the cap or cover 9 may be slid on over the pen end of the holder to protect those parts.

We are aware that it has beenbefore proposed to inclose the whole pen in a bag or case of sheet india-rubber, which case was opened by the separation of the nibs by pressure on the surface to be Written. The pen, if of corrodible metal, soon suilers from corrosion by the action of the ink by which it is surrounded constantly; but such plan is iniinieal to one veying bag I), in combination with a pen, the

nibs of which project through both sides of the bag, substantially as shown and described.

2. In a reservoir-pen, the combination of the ink-conveyin g bag with a pen which punctures and projects through both sides of the same, the pen-points being covered with a luting or coating of india-rubber or other suitthe combination, with a pen or nib, of an e1as-- tic inlesupplying bag, I), applied thereto, as

shown and described, andthrough the opposite sides of which thenibs of the pen project, and a reservoir ink-l1older arranged to supply ink to such bag, all substantially as shown and described.

4. In a writing instrument or pen, the combin ation of a pen or nib having an ink-supplying bag through which the nibs of the pen project, and luted' or coated with an elastic solution, as set forth, with a socket, c, reservoir (l, cylindrical piece a, plug f, and cap 9, air-passages, and an ink catchment chamber being provided in the respective parts, all

substantially as shown and described.

In witness whereof we, the said GIBBARD Bron ARD Hucuns and THOMAS CARWARDINE, aifix our signatures in the presence of two witnesses.
